<p>The <code class="literal">simple_query_string</code> query supports the following operators:</p>
<div class="ulist itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
<code class="literal">+</code> signifies AND operation
</li>
<li class="listitem">
<code class="literal">|</code> signifies OR operation
</li>
<li class="listitem">
<code class="literal">-</code> negates a single token
</li>
<li class="listitem">
<code class="literal">"</code> wraps a number of tokens to signify a phrase for searching
</li>
<li class="listitem">
<code class="literal">*</code> at the end of a term signifies a prefix query
</li>
<li class="listitem">
<code class="literal">(</code> and <code class="literal">)</code> signify precedence
</li>
<li class="listitem">
<code class="literal">~N</code> after a word signifies edit distance (fuzziness)
</li>
<li class="listitem">
<code class="literal">~N</code> after a phrase signifies slop amount
</li>
</ul>
</div>
<p>To use one of these characters literally, escape it with a preceding backslash
(<code class="literal">\</code>).</p>
<p>The behavior of these operators may differ depending on the <code class="literal">default_operator</code>
value. For example:</p>
<div class="pre_wrapper lang-console">
<pre class="programlisting prettyprint lang-console">GET /_search
{
    "query": {
        "simple_query_string" : {
            "fields" : ["content"],
            "query" : "foo bar -baz"
        }
    }
}</pre>
</div>
<div class="console_widget" data-snippet="snippets/165.console"></div>
<p>This search is intended to only return documents containing <code class="literal">foo</code> or <code class="literal">bar</code> that
also do <span class="strong strong"><strong>not</strong></span> contain <code class="literal">baz</code>. However because of a <code class="literal">default_operator</code> of <code class="literal">OR</code>,
this search actually returns documents that contain <code class="literal">foo</code> or <code class="literal">bar</code> and any
documents that don’t contain <code class="literal">baz</code>. To return documents as intended, change the
query string to <code class="literal">foo bar +-baz</code>.</p>

</h4>
</div></div></div>
<p>You can use the <code class="literal">flags</code> parameter to limit the supported operators for the
simple query string syntax.</p>
<p>To explicitly enable only specific operators, use a <code class="literal">|</code> separator. For example,
a <code class="literal">flags</code> value of <code class="literal">OR|AND|PREFIX</code> disables all operators except <code class="literal">OR</code>, <code class="literal">AND</code>,

<p>The <code class="literal">simple_query_string</code> query supports multi-terms synonym expansion with the <a class="xref" href="analysis-synonym-graph-tokenfilter.html" title="Synonym graph token filter">synonym_graph</a> token filter. When this filter is used, the parser creates a phrase query for each multi-terms synonyms.
For example, the following synonym: <code class="literal">"ny, new york" would produce:</code></p>
<p><code class="literal">(ny OR ("new york"))</code></p>
<p>It is also possible to match multi terms synonyms with conjunctions instead:</p>
<div class="pre_wrapper lang-console">
<pre class="programlisting prettyprint lang-console">GET /_search
{
   "query": {
       "simple_query_string" : {
           "query" : "ny city",
           "auto_generate_synonyms_phrase_query" : false
       }
   }
}</pre>
</div>
<div class="console_widget" data-snippet="snippets/169.console"></div>
<p>The example above creates a boolean query:</p>
<p><code class="literal">(ny OR (new AND york)) city)</code></p>
<p>that matches documents with the term <code class="literal">ny</code> or the conjunction <code class="literal">new AND york</code>.
By default the parameter <code class="literal">auto_generate_synonyms_phrase_query</code> is set to <code class="literal">true</code>.</p>
